Specification of Letters Patent. I Application filed July 1, 1913.

LQQLSOG.

To all whom it may concern.

Be it known that I, ANTONE' E. Dorm, a citizen of the United States, residing at Loyalton, in the county of Sierra and State of California, have invented new and useful Improvements in Bearings, of which the following is a specification.

The invention relates generally to an im provement in bearings and particularly to a bearing designed for the running shafts of a separator, the construction providing convenient access to the bearing to permit adjustment and renewal of parts when necessary.

The main object of the present invention is the provision of a bearing in which the various parts are separable in a ready and convenient manner to permitaccess to the bearing proper for adjusting.

The invention in its preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in

which Figure 1 is a view in elevation of the improved bearing. Fig. 2 is a central longitudinal section of same. Fig. 3 is a transverse section. Fig. 4c is a view in elevation showing the parts in separated or spaced relation.

The improved bearing comprises a casing 1 made up of two sections 2 and 3. The section 2 is of rectangular outline and formed with a semi-spherical depression 4 communicating with an opening 5 which extends centrally through the section beyond the depression. The side and end walls of the section beyond the depression are reduced forming shoulders 6, said walls extending beyond the rounded seat of the depression 4, and the opposing pair of said walls formed with openings 7. The section 3 which is arranged to cooperate and interfit with the sections 2 to form an inclosed housing includes a member having an end plate 8 preferably circular in section, from which project walls 9 of rectangular outline, the inner surface of said walls being spaced apart to snugly receive the walls of the section 2, the free edges of the walls 9 bearing against the shoulders 6 on the section 2. The end plate 8 of the section 3 is formed on its inner surface with a rounded depression 10 on the Patented Mar. 24, 1914. Serial No. 776,818,

radius corresponding to that of the semispherical depression 4 of, the section 2, said end wall 8 being further formed with an openmg 11 therethrough alining with an openmg 5 in the section 2, when said sectlons are assembled. The walls 9, or that opposing pair thereof which cooperate with similarly formed walls of the section 2, are formed with openings 12 adapted to register with the openings 7 when the sections are assembled.

An approximately spherical bearing member 13 is arranged to cooperate with the sections being of a size to fit more or less snugly within the depressions 4- and 10 in the completed bearing. The member 13 is formed with a diametrically extending opening 14 to receive the shaft, and at diametrically opposlte points with a plane or flatsurface 15.

In assembled relation, the member 13 is arranged between the sections and the latter in effect telescoped to the limits permitted by the described formation of their walls, after which screws 16, either in the form of machine bolts or ordinary headless screws are passed through the alined openings 12 and 7, seat in the depressions 15 in the bearing member. The shaft 17 is then passed longitudinally through the bearing, or the bearing moved lengthwise the shaft to the desired point, as illustrated in the drawing.

It Will be noted that the openings 5 and 10 in the respective sections have a diameter exceeding that of the shaft 17, while the depressions 15 in the bearing member are of greater length than the diameter of the locking screw 16. By this means a limited play is permitted the bearing member and shaft, thereby providing for the necessary vibrations without undue heating of the bearing. Furthermore by reason of the peculiar construction of the parts, the bearing members may be readily and conveniently separated for adjustment and renewal.

What is claimed is The combination with a shaft, of a bearing therefor including a casing, comprising telescopically arranged sections formed with alined shaft openings exceeding the diameter of the shaft, the interior of the casings being formed to provide an approximately spherical chamber, the walls of thecasings beyond the, chamber being formed with 'are in connected relation, a spherical bean openings adapted to aline when the casings also to secure the sections against separation.

In testimony whereof I aflix my signature in presence of two Witnesses.

ANTONE E. DOTTA.

1O ing member having an axial opening for the reception of the shaft, and means passing through the alined openings of the casing and engaging said bearing member, said means serving to secure the bearing member against independent rotative movement and Vitnesses:
